What 46615 covers

This service combines examination of the anal canal through an anoscope with destruction of one or more identified lesions. It may be used to treat anal condyloma or dysplastic lesions when the clinician selects an ablative approach, such as cautery or another method that destroys the target tissue. Colorectal surgeons and other clinicians trained in anorectal procedures commonly perform it in an office or procedure-room setting, or in a facility. It is distinct from a diagnostic anoscopy and from procedures that remove a lesion for examination as a specimen.

Report the service when documentation supports anoscopic visualization and treatment by ablation, and identifies the lesion or lesions treated. Do not select it merely because a lesion was observed or sampled; biopsy and removal methods have separate codes. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgery and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

46615 billing questions

How is this different from diagnostic anoscopy?

This code is for anoscopy that includes ablation of one or more lesions. Use a diagnostic anoscopy code when the examination is performed without lesion ablation.

Can this code be reported when a lesion is biopsied?

The service described here is ablation, not biopsy. If tissue is sampled or removed for pathology, select the code that matches the documented biopsy or removal technique rather than treating this as a biopsy code.

How does it differ from anoscopic lesion removal?

Choose an anoscopic removal code when the clinician removes a lesion using the technique specified by that code. This code describes destruction of lesion tissue by ablation.

What documentation supports reporting it?

Document anoscopic visualization, the lesion or lesions treated, and the ablative treatment performed. The note should distinguish ablation from biopsy or physical removal.

What happens when another related endoscopy is performed at the same session?

CMS endoscopy-family pricing applies when related endoscopies are performed together. The claim should reflect the services actually performed and their relationship.

Can modifier 50 or an assistant-at-surgery modifier be used?

Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for the service; co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
